IMPROVEMENT IN COOKlNG-STOVES.

Specification forming part of Letters Patent No. 42,432, dated April 19,1864.

To aZZ whom it may concern.-

Be it known that I, ADDIS E. CHAMBER- LAIN, of Cincinnati, Hamiltoncounty, Ohio, have invented a new and useful Improvement inCooking-Stoves; and I do hereby declare the following to he a full,clear, and exact description thereof, reference being had to theaccompanying drawings, making part of this specification.

My improvement relates to an improved manner of applying and securing adeflecting plate or screen within the fire-chamber of a cookingstove, ashereinafter described.

Figure 1 is a longitudinal section of the fire chamber and hearth of astove provided with my improvement. Fig. 2 shows my screen detached fromthe stove. Fig. 3 represents the broiling-cover. Fig. 4 is a horizontalsection through one end of my screen.

A, B, C, D, and E represent, respectively, the fire'chamber, theash-pit, the top and front plates, and thesliding hearth of an ordinarycooking stove.

F represents my deflecting plate or screen, so fixed in the stove as tointervene between the fire and the firedoors, and, by inclining inwardlytoward its lower part, acting to lead the draft to the under side of thefire near its mid-width, the draft. being in this way applied to thefire in the most et'fieient manner and the entrance of cold air directto the flue prevented.

G G are wings, which, projecting forward from the ends of the plate F,flank the door opening on each side and shut out the external air.

.An inwardly-projecting flange, H, at the bottom of the screen acts tostiffen the plate and to conduct the draft well to the middle of thefire.

The plate F is still further stiffened and protected from too directcontact of the fire by, means of flutings I.

Beside the customary projections employed to confine stove-plates intheir places, my plate F is additionally secured by means of ears J J,which are confined between the cus' tomary clamp-rods and the frontplate, D. The plate 13 is perforated near its top and provided with asliding register, K, which being opened, the effinvia of broiling isenabled to escape into the fire.

I The register K may also be opened purpose of checking combustion.

L is a cover, which, being placed upon the hearth when the stove isbeing employed for broiling, serves to expedite the cooking action andto confine the effluvia. l are air-inlets in the cover L.

I claim herein as new and of my invention- The deflecting plate orscreen F, constructed as described, with cheeks G G, flange H, ears J J,and a register, K, the said screen being secured within thefire-chamber, as herein specified, and for the purposes set forth.

In testimony of which invention 1 hereunto set my hand.
